This invention relates to an inking mechanism particularly adapted for use in newspaper printing presses.

The principal object of the invention is to provide means for arresting and condensing the fog of ink which is always present in some degree in a rotary inking mechanism run at high speed and to provide means for draining any ink thus entrapped and condensed back into the fountain in such a way that there will be no necessity of cutting open the back of the usual fountain mechanism.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing which is an end view of part of an inking mechanism with a preferred embodiment of this invention applied thereto, the parts except the rolls of the inking mechanism being shown in section.

The invention is shown as applied to the usual type of fountain 10, fountain roll 11, pick-up roll 12 and ink drum 13. The pickup roll and ink drum are not in contact but ink is transferred from one to the other by a pair of transfer rolls 14 and 15. The fountain roll is provided with the usual blade 16 for keeping the film of ink uniform on its surface. The ink drum runs at paper speed and so does the pickup roll. The pick-up roll performs its usual function of picking up ink from the fountain roll and transferring it to the lower transfer roll which puts the ink on the upper transfer roll and that applies it to the ink drum. The rest of the inking mechanism is not shown and it is not intended that this invention is necessarily a plied to these particular parts. It can e used at any point in the inking mechanism where a fog of ink is produced.

Where any two rollers part, there is generated a mist or fog of ink especially when running at high speed. When this fog is al-. lowed to drift through the press room it causes unsightly accumulations on everythin on which'it condenses and the ink is wasted. In order to avoid this I provide a shield 17 so located that it acts as an interceptor and condenser of the ink fog which comes out from between a pair of rolls or cylinders operating at high speed. The ink fog having no place to go except toward this 1 shield is deposited thereon and after awhile accumulates so as to drain back downwardly.

In the present case I have shown it as slanting down at an angle so as to drip down on the fountain roll where it projects above the fountain itself. Thiseliminates the necessity of cutting open the back of the cover. The shield is located close to the inking rolls because this ink fog when first generated lies near their circumferences. Thus it has no chance to escape into the room before it is condensed.

This shield 17 extends preferably throughout the length of the rolls near which it is piaced. In the form shown it is made as close as possible to the rolls 14 and 15. Several places where it gathers ink are between the rolls 13 and 15 and the rolls 12 and 14 but as the fog is carried around by the roll 14 it may be deposited on the shield anywhere along the line where this roll is close to the shield.

In this waythe fog is practically all taken care of along regions where the shield is located and prevented from getting out into the room and finally being deposited on the machinery and elsewhere. A certain amount of ink is saved and dropped back on the fountain roll where it is immediately used over again. This is a very simple device and the shield can be formed with flanges 18 at both ends by which it is secured to the framework of the press or inking mechanism.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by anyperson skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect but what I do claim is I 1. The combination with an inking mechanism comprising rolls and cylinders, of a shield located closely adjacent to the surfaces of a plurality of said rolls and cylinders for intercepting the ink fog that may be produced thereby and condensing it.

2. The combination with an inking mechaspeed nism comprising rolls rotating at high speed, of a shield located closely adjacent to certain of said rolls for intercepting the ink. fog that may be produced thereby and draining it back into a lower part of the inking mechanism.

3. In an inking mechanism, the combination with a pick-u roll, and a transfer roll for transferring t e ink from the pick-up roll, of a shield located closely adjacent to the circumference of the transfer roll for intercepting the ink fog and condensing it.

4. In an inking mechanism, the combination with a pick-up roll, an ink drum and transfer rolls for transferring the ink from the pick-up roll to the ink drum, said rolls rotating at high speed, of a shield located closely adjacent to the circumferences of the two transfer rolls for intercepting the ink fog produced at various places and draining it downwardly.

5. In' an inking mechanism, the combination with a fountain roll and rolls for transferrin the ink therefrom, rotating at a.

higher than that of the fountain roll, of a shield adjacent to the surfaces of certain of said rolls for intercepting the ink fog and allowing'it to drain down the shield, said shield having a lower port-ion extending down to a point to allow the condensed ink to drop directly on the surface of the fountain roll.

6. The combination with the inking mechanism for a printing press comprising ink carrying rollers, of a concave surface adjacent to one of the said rollers for condensing the atomized ink which is thrown off by the said rollers.

7. The combination with the inking mechanism for a printing press comprising ink carryin rollers, means adjacent to the said rollers or condensing the atomized ink which is thrown off by the said rollers, and means for leading the condensed ink into an inkholding receptacle.

8. The combination with the inking mechanism for a printing press comprising ink carryin rollers, means adjacent to the said rollers or condensing the atomized ink which is thrown off by the said rollers, and means for leading the condensed ink into an ink fountain.

In testimony whereof I have hereunto affixed my si ature.
